I wonder if studying in France offers more opportunities than studying abroad, for exeample in the « "American »" or Canadian education systems.

or "would offer," or "will offer"
I just assumed « is "? Don't know what those symbols mean eheh.

However, the jobs requires at least a master’s degree, whitch leads to a later entry into professional life with slower career and salary progression.

In contrast, in the US or Canada, education is more expensive, but a bachelor’s degree is generally sufficient to access to many professional opportunities with a better salary progression.

or "to give access to many"
or "with better salary progressions"

At least more so than in France.

"more so than" talks about the degree of sufficiency
it's MORE sufficient
"more than" can refer to frequency of occurrence, but since the previous sentence is expressing a state and not an action, it sounds off...
But I think this distinction would slide under the radar in speech.

PIt's probably thatbecause the French system prioritizes academic degrees while the American system prioritizes practical experience and rapid career development.
